think of it this way which insult seems more extreme to you a fuck you asshole b fuck you nigger you hear the first one multiple times a day yet the word nigger isnt used that often because of how stigmatized you get for using it now if it was used as often as other curse words that have basically lost all power eg fuck shit cunt bitch etc it would lose its power ofc a slurs power doesnt come exclusively from how often its used but its definetely a big factor op wasnt saying the word nigger would stop being an offensive word but that it wouldnt hold nearly as much power
